JOHN HENRY KNIGHT, 0F BARFIELD, FARNHAM, ENGLAND;

TIRE non Moron AND OTHER ROAD-VEHICLES.

Application filed August 25,

To all whom it may concern:

Be it known that I, JOHN HENRY KNIGHT, a subject of the King of Great Britain, residing at Barfield. Farnham, Surrey, England, have invented certain new and useful Improvements in Tires for Motor and other Road-Vehicles, of which the following is a specification.

This invention relates to tires for the wheels of motor and other road vehicles which are composed of blocks of wood, and it consists of an improved construction whereby the wearing properties of such tires are materially increased, and the mounting and dismounting of the blocks is facilitated. I attain these ends by the construction shown in the accompanying drawing in which 2- Figures 1 and 2, are broken views in elevation and plan respectively showing the improved construction of the blocks, and Figs. 3 and 4c, are broken views in side elevation and transverse sections respectively showing the improved method of mounting the blocks on the rim or felly of the wheel.

Throughout the views similar parts are marked with like letters of reference.

The blocks of wood a are of a rectangular or approximately rectangular shape and are shaped'on their undersides to fit the contour of the rim or felly e of the wheel. In the ends of the blocks-which are so cut that the grain of the wood runs length-wise of the blockare cut V-shaped recesses a, and above said recesses are a series of saw cuts a which together form a series of tongues a at the ends of the blocks.

In some cases the upper part of the block may be built up of a series of flat pieces of wood which are held together at or about their centers, which attains the same ends as the saw cuts.

To render the blocks more durable and to preserve their resiliency, they may be soaked or otherwise treated with oil or other suitable material.

To protect the blocks from undue wear, their ends are shod with metallic blocks or studs 6 which are carried by thin metal plates 0 of any suitable flexible metal. These plates 0 are fixed to the blocks a by bolts d which may also be employed as shown in Figs. 1 and 2 to the blocks to the wheel rim e. A stirrup piece f of suitable metal is laid over the plate 0 and the top of the block a to form a cap washer for the bolts, and said cap washer also operates Specification of LettersPatent.

I to prevent the block from Patented Mar'.14, 1916.

1913. serialld'o l'sfifils splitting. The blocks or studs 6 are arranged to lie at an angle with the face of the wooden blocks a so that they impart a beveled formation to the front and back edges of same, the result of which is that said blocks or studs present tangential surfaces when the wooden blocks are mounted on the wheel rim.

For wheels for heavy vehicles the wooden blocks a are arranged in two or more rows placed side by side, in which case they are preferably stepped as shown .in Fig. 2, and when the blocks are arranged in such a manner they are preferably fixed to the'wheel rim 6 in the manner shown in Figs. 3 and 4 which consists in making the bases of the blocks of-a dovetail shape and clamping the roWs of blocks and intermediate spacing rings 71. of a wedge shape in cross section together and to'a wheel rim 6 having incurved side flanges e by means of a series of transverse bolts m one flange e of the rim being detachable for the purpose of getting the intermediate spacing rings h and the blocks a into position. In this construc-' tion the bolts d do not pass through the wheel rim but only through the blocks a, the plates 0, and the stirrup piece f, but plates or washers it maybe employed on the undersides of or nuts of the bolts d to bear against.

What I claim'as my invention, anddesire to secure by Letters Patent is V 1. VA tire for motor or other road vehicles, comprising a series of blocks of wood in the ends of which are cut recesses following the grain of the wood, flexible metal plates secured to the outer faces of said blocks, and

metallic blocks or studs carried by said plates.
